Findings on neurocognitive effects of sustained cannabis use are heterogeneous. Previous work has rarely taken time of abstinence into account. In this review, we focus on understanding sustained effects of cannabis, which begin when clinical symptoms of the drug have worn off after at least 14 days. We conducted a search between 2004 and 2015 and found 38 studies with such a prolonged abstinence phase. Study-design quality in terms of evidence-based medicine is similar among studies. Studies… 
Neurocognitive consequences of chronic cannabis use: a systematic review and meta-analysis
TLDR
There was a low cross-sectional association between neurocognitive impairments and chronic cannabis use in cognitive impulsivity, cognitive flexibility, attention, short-term memory and long- term memory.
Adverse Effects of Cannabis Use on Neurocognitive Functioning: A Systematic Review of Meta- Analytic Studies
Abstract Objective: As the perceived risk of cannabis use continues to decline among youths and access continues to increase, it has become more important to synthesize the rapidly growing literature
Heavy cannabis use, dependence and the brain: a clinical perspective
TLDR
Current evidence of long‐term effects of daily cannabis use and cannabis use disorder on brain‐related outcomes is suggestive rather than conclusive, but use is associated with psychiatric morbidity and with cognitive impairments that recover after a period of abstinence.
Interactions between recreational cannabis use and cognitive function: lessons from functional magnetic resonance imaging

TLDR
Although it is clear that cannabis affects brain function, the findings are somewhat inconsistent; variables that potentially affect study outcomes are outlined, including a discussion of the impact of chronological age and age of cannabis onset as well as length of abstinence at the time of assessment.
Cognitive outcomes associated with long-term, regular, recreational cannabis use in adults: A meta-analysis.
TLDR
The results suggest that long-term, regular cannabis use is associated with small to moderate deficits in some cognitive domains, while decision making had moderate deficits.
Does Cannabis Consumption Negatively Affect Cognition? A Review Of The Scientific Evidence
Objective: This review summarises the existing evidence on the effects that recreational and medical use of cannabis and cannabinoids have on cognitive performance. Methods: Databases (PubMed,
The neurocognitive effects of a past cannabis use disorder in a diverse sample of people living with HIV
TLDR
Findings suggest PLWH with past cannabis use have similar or better neurocognition across domains compared to PLWH without past use.
Impact of 2 Weeks of Monitored Abstinence on Cognition in Adolescent and Young Adult Cannabis Users
TLDR
Deficits in attention, but not verbal learning and memory, recovered after 2 weeks of monitored abstinence, suggesting that other cognitive domains may show signs of recovery after periods of cannabis cessation in adolescents and young adults.
Association of Cannabis With Cognitive Functioning in Adolescents and Young Adults: A Systematic Review and Meta-analysis
TLDR
Results indicate that previous studies of cannabis in youth may have overstated the magnitude and persistence of cognitive deficits associated with use and suggest individual differences in susceptibility to cannabis-associated cognitive dysfunction should be examined.

Effects of Cannabis on Impulsivity: A Systematic Review of Neuroimaging Findings
TLDR
To address the question whether impulsivity as a trait precedes cannabis consumption or whether cannabis aggravates impulsivity and discontinuation of usage more longitudinal study designs are warranted.
Residual effects of cannabis use on neurocognitive performance after prolonged abstinence: a meta-analysis.
TLDR
Overall, these meta-analyses demonstrate that any negative residual effects on neurocognitive performance attributable to either cannabis residue or withdrawal symptoms are limited to the first 25 days of abstinence and there was no evidence for enduring negative effects of cannabis use.
The chronic effects of cannabis on memory in humans: a review.
TLDR
The impact of not only specific parameters of cannabis use in the manifestation of memory dysfunction, but also such factors as age, neurodevelopmental stage, IQ, gender, various vulnerabilities and other substance-use interactions are considered, in the context of neural efficiency and compensatory mechanisms.
Effects of Cannabis on Neurocognitive Functioning: Recent Advances, Neurodevelopmental Influences, and Sex Differences
TLDR
The purpose of this review was to provide an update on research of cannabis’ acute and non-acute effects on neurocognition, with a focus on findings since 2007, and suggest and discuss how neurodevelopmental issues and sex differences may influence cannabis effects on neuroscience.
The residual neuropsychological effects of cannabis: the current status of research.
Structural and Functional Imaging Studies in Chronic Cannabis Users: A Systematic Review of Adolescent and Adult Findings
TLDR
Chronic cannabis use may alter brain structure and function in adult and adolescent population and functional neuroimaging studies suggest different patterns of resting global and brain activity during the performance of several cognitive tasks both in adolescents and adults may indicate compensatory effects in response to chronic cannabis exposure.
The effect of cannabis use on memory function: an update
TLDR
Future experimental and epidemiological studies that take into consideration individual differences, particularly previous cannabis history and demographic characteristics, but also the precise mixture of the ingredients of the consumed cannabis are necessary to clarify the magnitude and the mechanisms by which cannabis-induced memory impairments occur and to elucidate underlying neurobiological mechanisms.

TLDR
Although there is only equivocal evidence that chronic cannabis use might result in structural brain changes, blood-oxygenation-level-dependent-fMRI studies in chronic users consistently show alterations, or neuroadaptation, in the activation of brain networks responsible for higher cognitive functions.
An Evidence-Based Review of Acute and Long-Term Effects of Cannabis Use on Executive Cognitive Functions
